Oil fired thermal oil boilers is a boiler with coal, heavy oil, light oil or combustible liquid as fuel and heat-conducting oil as heat carrier. Then a circulating oil pump is used to force the liquid phase to circulate the heat energy to the heat equipment, and then the heat energy is returned to the reheated special type industrial furnace. This series of organic heat carrier boilers are widely used in petrochemical, textile, printing and dyeing, plastic, rubber, food processing, wood processing, asphalt heating, carton production, vegetable dehydration, paint baking, casting sand mold drying and so on.
This series of thermal oil boiler can obtain higher working temperature under lower operating pressure. Stable heating and precise temperature can be obtained. Thermal efficiency is maintained at a good level at all levels of load. The liquid phase transports the heat energy, at 300℃, the heat carrier is 70 times less than the saturated steam pressure of the water. It has complete operation control and safety monitoring device.
The oil fired thermal oil boilers has the characteristics of low pressure, high temperature, safety, high efficiency and energy saving. With complete operation control and safety monitoring device, the working temperature can be precisely controlled. Reasonable structure, complete supporting facilities, short installation cycle, easy operation and maintenance, easy to boiler layout. The adoption of explosion-proof electrical heating organic heat carrier furnace structure, can be applied to the factory Ⅱ explosion-proof, explosion-proof grade can reach grade C.
In the production practice, the coking thickness of thermal oil boiler is safe below 2mm, and the coking layer in the furnace tube is between 0~1.5mm. At this time, the continuous storage of the coking layer is roughly balanced with the amount of melting washed by the heat carrier. The thickness of the coke layer in the furnace tube can be determined by an ultrasonic thickness meter. A filter should be installed in the circulation pump population to filter out the chemical changes resulting in the suspension of the polymer and the local overheating of carbon particles. The filter should be easy to disassemble and replace, so as to clean up the residue and impurities regularly to ensure the filtering effect.
When cleaning, to check whether the heating furnace and its surrounding clean without sundries, check the furnace body, burner, controller, see the fire hole, smoke (chimney) path is normal; Check whether the oil level of the expansion tank is above 1/4 to 1/2 liquid level and whether the thermometer and pressure gauge are normal; Switch on the heating furnace control cabinet, check whether the voltage is normal, check whether the indicator light and each display instrument are normal; Adjust the gas main pressure reducing valve and secondary pressure reducing valve to control the pressure to 0.005mpa.
